“…2. The effect of balconies on direct solar radiation and consequent reduction in energy demand for cooling in 21-story residential building in Hong Kong was studied by Chan [30]. It was presented that effectiveness of a balcony, in terms of solar shading, may vary for identical residential flats located on different levels of a building.…”

In this work, the unsteady turbulent flow in a new solar air heater test bench, developed in our LASEM laboratory, was predicted. The considered system consists of two passages solar air heater separated by an absorber and powered by a fan working in a delivery mode, placed in the hole inlet side the insulation. On this system, a glass is hanging on the front side and an absorber is inserted inside. On the glass side, it is connected to the box prototype through a pipe. The hot air flow is routed towards the box prototype. Two circular holes, are located in the same face of the box prototype. The inlet hole allows the hot air supply. However, the outlet hole allows its escape into the ambient environment. By using the ANSYS Fluent 17.0 software, the Navier-Stokes equations coupled with the standard k-ω turbulence model were resolved. The numerical results were compared with our experimental data, established in the second passage of the solar air heater test bench. The good agreement confirms the validity of the numerical method. The range of temperatures is very useful in many applications such as industrial and domestic applications.

“…Many building electricity analyses focus on the individual building level. For example, Chan investigates the optimal height for installing balconies on residential buildings in order to maximize the solar shading benefits [4], and Pan et al examine green building design options to improve two office buildings in Shanghai, China [5]. However, extrapolating from a single building to predict a larger area may fail to capture the variability between different types of buildings and different habits of users.…”

Within residential electricity consumption there exists significant variability from home-to-home due to the differences in building thermal properties, appliances, and inhabitants. Electricity analyses at sub-city scales using predefined geographies, such census tracts, might artificially split areas with homogenous characteristics leading to analyses that don't effectively contrast the drivers of energy use. The objective of this study is to use the spatial relationships between demographics, building types, and electricity consumption to form new geographies with less variability for use in residential energy assessment. Using Los Angeles and New York City as case studies, differences in variability of energy use within predefined geographies (e.g., census tract) are compared to geographies defined by clustering on socio-technical characteristics. Socio-technical clustering, regardless of the chosen subset of variables, reduces the variability over pre-defined geopolitical boundaries with high statistical significance (p << 0.0001). By clustering for energy analysis, intra-regional variability is reduced by 13% in Los Angeles and 29% in New York, improving opportunities for prediction and forecasting. This is the first study to examine the role of spatial boundaries in urban energy assessment. The creation of socio-technical geographies for electricity assessment creates opportunities for improving predictions and forecasts for future sub-and cross-city energy studies.
